Installation of the split ring
Here is how the split ring attaches to the scope.
(assuming the sunshade is off of the scope)
Step 1: Slide the split ring over the objective end of the scope and let it set just in front of the turrets.
Step 2: Slide the sun shade over the objective end of the scope and move it all the way to the rear (retracted)
Step 3: Holding onto the sun shade, start placing the split ring under the rear edge of the sunshade. There is a small lip at the rear of the sunshade (inside) that the split ring snaps into. Just start at one end of the ring and work your way around.
